He very definitely served overseas in a theatre of war, as he wouldn't have been entitled to the British War and Victory medals otherwise. Interestingly, there is a notation on his medal index card that shows that either the medals were never delivered and they were returned, or that there must have been an error on the original medals that he was sent and they were returned to be corrected and reissued. This is indicated by the notation "Retd (1743 K.R. 1912) 8100/Adt" on the card. The key is the last part of the notation, if this was Adjt instead of Adt, it would mean that the medals were returned to be corrected and reissued, in this case however, I think the implication is that they were never delivered and were instead returned for disposal.
